Joining technology of CP-Titanium and Titanium alloy is very important for manufacturing field. In that case of titanium brazing, chemical compositions of brazing filler metal and brazing atmosphere are very important. In this study, Ti alloy (Ti-6Al-4V)/Stainless Steel (SUS630, PH stainless steel) were brazed with Ag-based brazing filler metal foil (Ag-Cu eutectic composition) and Ti-based laminated brazing filler metal foil by using continuous type furnace under Ar gas atmosphere containing extremely low oxygen. Laminated filler was fabricated by roll bonding technology. Whole chemical compositions of laminated filler metal used in this study were Ti-15Cu-15Ni and Ti-20Zr-20Cu-20Ni. Brazing condition employed in this study in that case of laminated brazing filler metal was 950 C and 30 min. And brazing conditions employed in this study in that case of Ag-based brazing filler metal were 830C 3 min, 830C 30 min, 860C 5 min and 900C 5 min. Joint characteristics were estimated by micro-structural observation at the joint and mechanical properties measurement. Sound joint was obtained in this study according to outside appearance of the specimen and cross-sectional microstructure.
